Answer 1

The correct option is C 38.89

Total Exports of Six Countries
$\begin{array}{cccccc}Year& 2011& 2012& 2013& 2014& 2015\\ Country& & & & & \\ P& 20& 40& 60& 45& 90\\ Q& 30& 25& 15& 50& 100\\ R& 50& 55& 70& 90& 65\\ S& 45& 60& 20& 15& 25\\ T& 60& 50& 55& 100& 110\\ U& 24& 40& 60& 75& 120\end{array}$

$\begin{array}{cc}1999& 2001\\ 40& 45\\ 25& 50\\ 55& 90\\ 60& 15\\ 50& 100\\ \frac{40}{270}& \frac{75}{375}\end{array}$

$\therefore$ Difference = 275-270=105
$\therefore$ Percentage Growth $=\frac{105}{Totalexportin1999}\times 100=\frac{105}{270}\times 100=\frac{350}{9}=38.89$
